Each set of brushes preferably comprises a pair of side brushes II]having axially-extending bristles II and a toe brush I2 having radiallyextending bristles I3, the aXially-bristled brushes I being adapted tosnugly engage the opposite sides of a shoe I4 with the radially-bristledbrush I2 adapted to likewise snugly engage the toe portion of the shoeI4 when the shoe is placed on the support I5 and moved forwardly to thebrushing zone on the guides I3 through the opening I8 in the casing I1.Each of the aXially-bristled brushes I0 is carried by a stub shaft ISjournalled for rotation in the lower end of a supporting arm 20 hingedlyconnected at 2I adjacent the upper end thereof to one of the supportingelements 23 of a composite bracket 22 to permit lateral swingingmovement of the brushes I0, each bracket 22 comprising integrallyconnected sup.-

porting members 23, 24. The brushes Il of each set are constantly urgedtoward each other and toward and against the shoe I4 by the action ofhelical tension springs 25, each of which is attached at one end to alug 26 of its respective arm and at the opposite end to the cross brace21 of the bracket 22. The radially-bristled brush I 2 of each set ismounted on a shaft 28 journalled for rotation in the ends of a pair ofsubstantially horizontal supporting arms 29 pivotally carried at 3U bythe lower ends of the supporting element 24 of the composite bracket 22to permit vertical swinging movement of the brush I2, and the brush I2of each set may preferably be constantly urged downwardly toward andagainst the toe of Vthe shoe I4 by the action of a helical compressionspring 3| coacting with the support 24 and the brush supporting arm 23.lThe entirev brush assemblages hereinabove described, includn ing twosets or series of brushes for right and left shoes, are all swingablysuspended from a common shaft 32 which carries each of the compositebrackets 22, and the brushes are all adapted to be simultaneouslyoscillated relative to the shoes I4and their supporting members I5 in amanner to be hereinafter more fully described.

To drive the sets of brushes, a motor 35 and a series of motiontransmitting chains and sprockets and belts and pulleys or sheaves areprovided. The motor 35 directly drives a sprocket 36 which, in turn, isconnected by a chain 31 to a sprocket 38V for transmitting rotary motionthereto. Keyed to the shaft 39 of the sprocket 38 for rotation therewithis a pulley or sheave 43 adapted to drive a belt 4I and transmit rotarymotion therethrough to a pulley or sheave 42 keyed to the shaft 32. Alsokeyed to the shaft 32 for rotation with the pulley 42 is a series ofpulleys or sheaves 43, 44, each of the pulleys 43 carrying a belt 45adapted to transmit motion to a pulley or sheave 46 keyed to the shaftI9 of one of the brushes I0 for rotation of these brushes Ill and eachof the pulleys 44 similarly carrying a belt 41 adapted to .transmitmotion to a pulley or sheave 48 keyed to a shaft 49 which is journalledfor rotation in a pair of the arms 26 adjacent the pivotal connection30, each shaft 49 likewise hav ing keyed to it a sprocket 56 connected.by a chain 5I to a sprocket 52 keyed to the shaft 28 of each brush I2.Also. keyed to the shaft 35 for rotation with the sprocket 38 is asprocket 53 in turn connected by a chain 54 to a sprocket 55 keyed to ashaft. 56. The shaft 53 also carries a, crank 51 forv each set ofbrushes, each crank 51 being connected by a rod or pitman 53 to one ofthe brackets 22.

It is apparent from the foregoing that vduring operation of the motor 35rotary motion is transmitted to all of the brushes It through thesprocket 36, chain 31, sprocket 35, shaft 35, pulley 4I), belt 4I,pulley 42, shaft 32, pulleys 43, belts 45, pulleys 46 and shafts I9 androtary motion is similarly transmitted, to each brush I2 through thesprocket 36, chain`31, sprocket 52, shaft 35, pulley 45, belt 4I, pulley42, shaft 32, pulleys 44, belts 41, pulleys 48, shafts 49, sprockets 55,chains 5I, sprockets 52 and shaft 26. Simultaneously with the rotationof the brushes, oscillatory motion is transmitted thereto through thesprocket 36, chain 31, sprocket 38, shaft 35, sprocket 53, chain 54,sprocket 55, shaft 55, crank 5l' and connecting rod 58.

In addition to operating the brushes as here-y inabove described, themotor 35 drives a sheave 6I mounted on the motor shaft, motion from thesheave 6I being transmitted by a belt 52 to a sheave 53 mounted on theshaft of an air comu pressor 64 to drive the compressor. Air from thecompressor 34 is forced through a pipe 65V to an air storage tank 63 andfrom the storage tank 66 through a pipe 61 leading directly to the topof a shoe polish storage receptacle or tank 38 provided with a reliefvalve 5S. A pipe 1li leads from the lower portion of the polishreceptacle 63 below the normal level of the polish to a polish controland shut-off valve 'Il which is operable by a connection 12 toperiodically deliver successive batches of polish into a pipe 13 leadingfrom the valve 1I. The air supply pipe 61 also communicates, thro-ugh apipe 14, with another valve 15 which is operable by another connection13 to periodically deliver compressed air through a pipe 11. The lpipe11 communicates with the upper end of a polish ejection pipe 18 pasttheY lower extremity of the pipe 13, and the lower portion of the pipe15 is provided with outlet nozzles 19, which are directed respectivelytoward the brushes I2, I3. With this assemblage, Whenever air underpressure from the supply reservoir 55 is permitted to flow through Vthepipe 61 and the valves l, 15 are open, a slug of polish will bedelivered from the receptacle 58 and this slug will be transported bythe air delivered past the valve 15 into the pipe 18, by ejector action,from whence it willbe sprayed upon the brushes through the nozzles 1S,8i), branches of the pipe 18 leading to each series of brushes.

The control means for effecting actuation of the operating mechanismcomprises, a i'lXed locally-interrupted annular contact plate 83connected in the usual manner by wiring BI to one terminal of the motor35 and a peripherallytoothed control wheel 84 keyed to a shaft 85 andsuitably insulated from the plate 83 and connected to the other terminalof the motor 35 by wiring 32, the control wheel 84 having a laterallyprojecting pin 85 revolvable with the wheel in contact with the plate 83to provide a closed circuit and eifect operation of the motor. Radiatingfrom the shaft 35 carrying the wheel 84 is a pin 81, and when this pin81 is in vertical upwardly extending position as shown in Fig. l, thecontact pin 86 on the wheel 84 is adjacent the local interruption or gapin the plate 63 and out of Contact therewith and the motor 35 is therebyrendered inoperative.

To initially angularly displace the control wheel 84 so as to carry thepin 86 across the gap and into contact with the plate 33 to start themotor 35 and operate the brushes I6, I2, a ooin-receiving means isprovided which comprises, a slotted cover 88 forming a guide for alongitudinally slidable starting arm 80 having a through opening thereinwhich is alinable with the slot in the cover 88 to receive a coin of aparticular denomination, the arm 89 having an upright gripping portion9| at one end thereof and a downwardly inclined hingedly connectedactuating portion S2 at the opposite end adapted to abut the pin 81 andinitially angularly dis-i place the pin 86, shaft 85 and wheel 84 uponVirl-- sertion of the proper coin in the opening or slot 00 andsubsequent forward movement of the arm 80 by means of the grip 0| in anobvious manner, the coin falling through the opening 90 into a coinreceptacle 93 upon movement of the arm 8'9 a predetermined distanceforward. As the pin 86 is initially carried across the gap and intocontact with the plate 83 as described, the electrical circuit for themotor 35 is closed and the motor is thereby started, the brushes l0, I2being caused to rotate and simultaneously oscillate as hereinabovedescribed. A pawl 94 is pivotally carried by one of the elements 23 ofthe composite bracket 22, the free end of the pawl 95, coacting with theperipheral teeth of the control wheel 84 in a manner hereinafter morefully described. To maintain the pawl 90 in contact with the teeth 05, acoil tension spring 06 attached at one end to the medial portion of thepawl 94 and at the opposite end to a lug 01 on the element 2 0f thebracket 22 and a chain 0i! attached to a lug 99 on the pawl 91| and tothe bracket 22 are provided. As the bracket 22 and the brushes carriedthereby are oscillated by the driving means, including the crank 51 andpitman 5B, as hereinabove described, the pawl SM engages the teeth 95 ofthe control wheel 84 to rotate the wheel 84, shaft 05 and pin 81counteru clockwise by increments in an obvious manner. As the wheel 84approaches one complete revolution, `the inclined portion 92 of thesliding memher 89 is raised about its hinge |00 by the pin 81, fallingto position adjacent the pin S1 as the wheel 34 reaches the positionshown in Fig. l and cornes to rest with the pin B5 in the gap oftheplate 03 and out of contact therewith, thereby L halting the motorand operation of the brushes l0, f2.

The coin-controlled means for effecting simultaneous actuation of thebrush operating mechanism and the polish delivering means comprises, asimilar slotted coin-receiving cover and guide i0! for a longitudinallyslidable starting arm |02 having an opening therein for' receiving acoin of a different denomination, the arm |02 having an upright grippingportion substantially like the portion 0| of the arm 80 and additionallyhaving a lug |03 formed for coaction with the shoulder 04 on the member80 above the hinge |00 so as to slide the member or arm 80 and theactuating portion 92 thereof forwardly upon insertion 0f the proper coinand longitudinal forward movement ofthe arm |02, thereby initiallyangularly displacing the pin 81, shaft 85 and wheel 84 to carry the pin80 across the gap and into contact with the plate 33 and consequentlystart ing the motor 35 and operation of the brushes as hereinabovedescribed. The forward portion of the arm |02 is inclined downwardly at|05 and is adapted to coact with one arm of a `bell crank |06, as shownin Fig. upon forward movement thereof, the other arm of the bell crank|05 being cooperable `with the end of an axially movable `shaft |01journalled in bearings E08 to shift the shaft |01 laterally toward theside of the sprocket wheel during such forward movement of the 6. arm|02. A crank |09 is formed at the end of the shaft |01 adjacent thevwheel 55 and a lug l0, cooperable with the crank |09, is `provided onthe side of the wheel 55 so that when the wheel is driven by the motorand the shaft |01 is shifted as aforesaid with the crank |00substantially against the side of the wheel 55, the lug l |0 will.contact the crank |09 and rock the shaft |01 clockwise. An arm isrigidly attached at one end thereof to the shaft |01 for rockingmovement therewith, the swinging end of the arm carrying a rod H2rigidly connected. to the arms 12', 15 respectively associated withactuating mechanism H5, H0 for operating the valves 1|, 15 respectively.From Fig. 4, it will be noted that the arm 12 merely engages aperipheral notch ||1 in the actuating member or plate ||'5 of the valve1| which is constantly urged to clos ing position by a spring H8,whereas the rod 0r arm 15 is pivotally connected to the actuating leverH5 of the valve 15. Suchassemblage permits only momentary opening of thevalve 1| by movementof the arm 12 to the right as viewed inthe drawings,the end ofthe arm 12 becoming disengaged from the notch |1 during suchmove ment andthe spring instantly returning the valve actuating plate||5 to closed position. This momentary opening of the valve 1| howeverpermits a slug `or batch of polish to pass to the pipe 13 from thereceptacle 68 and this polish is then delivered, as hereinabove setforth, by ejector action of the compressed air passing through the openvalve 15 and pipes 11, 18, the valve 15 remaining open untilautomatically closed as hereinafter set forth. Also radiating from andrigidly attached to the shaft |l01 is a trip lever l adapted to berocked clockwise with the shaft |01 to engage a latch 20 simultaneouslywith the opening of the valves 1|, 15 as aforesaid, the latch |20 thusholding the lever H9, the shaft |01 and the arm in tripped and latchedposition. Another arm |21, radiating from and rigidly carried by theshaft |01, is attached at its free end to a coil tension spring |22which constantly urges the shaft |01 and parts carried therebycounterclockwise and the latch 20 is similarly urged counterclockwiseand against the trip lever l 9 bya coil tension spring l 23 coactingwith an arm thereof, thereby assuring retention of the trip lever I l0in tripped and latched position. The latch |20 is positioned adjacentthe side of control wheel 84 which has a `laterally` extending lug |24;and as the wheel 84 is rotated by increments in a counterclockwisedirection by the action of the pawl 04 with the peripheral teeth 95, thelug |20 is lmoved toward -ari arm of the pivotally mounted latch |210causing release of the lever HS from the latch |20 `as the lug E20contacts the latch arm. As the trip `lever iid is `disengaged from thelatch |120, the spring |22 causes the shaft |01 and the elements`carried thereby, including the arm to rock counterclockwise back to theposition shown in Fig. e, `thereby closing the air valve 15 through theconnections ||2, 16, and H6. The lug |24 is preferably so located thatthe valve 15 is permitted to remain open for only a relatively shorttime, sufficient to deliver the polish in the pipe 13- to the brushingZones through the pipe 18. To prevent backward rotation of the wheel 811`during all of the operations hereinabove described, a pivotally mountedlatch pawl |25 is provided, the latch i25 having one arm thereof`engaging the teeth and constantly urged into 7. engagement therewith bya coil tension spring |26 coacting with the other arm thereof.

While the operation of the improved unit is believed apparent from theforegoing detailed description, the operation may be briefly summai-izedas follows: The operator may rst preferably be seated on a seat providedon the support lli with his or her shoes IA; resting on the shoesupports l which are then slid through openings i8 forward on the guiderails i6 to a position between the brushes lli and with the toes of theshoes adjacent the brush l2. If it is desired to ymerely buff the shoeswithout application of polish, the proper coin is next inserted in theslot Sil and the operator may then slide the actuator 8S, S2 forwardlyby grasping the upright portion 9|. This operation initially angularlydisplaces the pin 8l and the wheel 84, thereby effecting contact of thepin 85 with the plate 83 and starting the motor 35. As the motorcontinues to operate, motion from its shaft is transmitted by sprockett5, chain 3l, pulley M, belt 4| pulley 42, shaft 32, pulleys t3, beltsP15, and pulleys i5 to the shafts i9 of the brushes i, causing thesebrushes to rotate with the axial bristles thereof constantly urgedagainst the opposite sides of the shoes It by means of the hinged andlaterally-swingable Varms 2G and cooperable coil tension springs 25.

At the same time motion from the motor shaft is transmitted by sprocket3B, chain 31, pulley Gil, belt 4l, pulley 42, shaft 32, pulleys 44,belts lll, pulleys'd, shafts Ml, sprockets .i, chains 5I, and sprockets52 to the shafts 28 of the brushes i2, causing these brushes to likewiserotate with the radial bristles thereof constantly urged against thetoes of the shoes lli by means of the swingable arms 2S and cooperablecoil compression springs 3 l. Simultaneously, the sprocket 53 on theshaft 39 drives the chain 54 and the sprocket wheel 55, causing theshaft 56 and crank 5'! to rotate and thereby effecting oscillation ofthe brushes iii, l2 through the connection of the pitman 58 with thecrank 51 and composite brackets 22. While the shoes l!! are thusthoroughly brushed by the rotating and simultaneously oscillatingbrushes il), l2, the oscillatory movement of the brackets 22 cause thepawl 94 to rotate the wheel 84 by increments through engagement with theperipheral teeth Q5 until the wheel 8d has made a complete turn and thecontact pin 8e reaches the gap in the plate St, at which time the switchis opened and further operation of the motor and brushes ceases.

If it is desired to receive a complete shine from themachine, includingthe application of polish, the proper coin must rst be inserted in theslot provided in the member H32 and the actuating member H32 then slidforward as described with reference to the actuator 73S. As the actuator|02 is moved forwardly, the lug H33 engages the shoulder lili on themember 89 and pushes the member 8e, 92 therealong, thus angularlydisplacing the pin 8l and starting the motor 35 and series of operationshereinabove described. In addition, the portion Het of the actuatorengages an arm of the bell crank liiii, causing the bell crank ll toshift the shaft IM' toward the wheel As the wheel 55 rotates the lug Ilthereof contacts the end of the crank |69, causing the shaft lill torock clockwise with the trip lever H9 thereby engaging the latch lZwhich holds the lever H9 and shaft lli'i in tripped and latchedposition. As the shaft lill is angularly displaced or rocked as aboveset forth, the arm IH is also rocked, thereby moving the rod l l2 andits actuating connections '52, 'i6 to the right and rotatingthe platesHE, l le for actuating the Valves 1l, 15 respectively to valve openingposition, the valve 'El opening only momentarily, due to the coaction ofthe arm l2 with the notch lll of the plate H5 and simultaneous action ofthe spring H8, to permit a slug of polish from the receptacle 68 toenter the pipe and the valve l5 remaining open, due to the pivotalconnection of the arm 16 with the plate 5&6, a sufficient length of timeto empty the pipe 'i3 of polish by ejector action of the compressed airpassing through the pipes TI, i8. During this valve actuating operation,the motor 35 is driving the compressor 54 through the sheave 5l, beltt2, and sheave 63 and compressed air is being delivered through the pipe65, tank 66 and pipe @l to the upper portion of the polish receptacleES. Consequently as the valve 'H is opened momentarily as aforesaid, aslug of polish from the receptacle is forced into the pipe 13 by airpressure in the receptacle; and as the Valve 'i5 is maintained open, airunder pressure delivered by the pipe El and thence through the pipe lil,valve l5, and pipes il, 'i8 draws the polish from the pipe it anddelivers the same to the brushes i2 through the nozzles i9, 80. As thewheel Se rotates as above-described, the lug Effi contacts an arm of thelatch l2i), pivoting the latch and disengaging the trip lever H9, thespring 22 then turning the shaft lill and arm i i i to its originalposition and causing closing of the valve Although the polish deliveringmeans is thus rendered ineffective, the brushes, iii, i2 continue tooperate on the shoes I4, being driven by the motor 35 until the wheel 84has been caused, by the coaction of the pawl 94 with the teeth tocomplete a revolution and carry the Contact pin to the gap in the plate83.

From the foregoing detailed description of the construction andoperation of my automatic shoe shining unit it is apparent that myinvention provides an improved coin actuated, motor driven machine whichis adapted to effectively buff and/or polish shoes of any size. Theimproved machine is relatively simple and compact in construction andthe polishing brushes are flexibly mounted so to receive and snuglycontact either mens, womens or childrens shoes. The improved mechanismhas proven highly successful in actual use and the unitary constructionof the machine permits the same to be transported and installed inlimited spaces. As is apparent from the foregoing detailed description,the machine is adapted to selectively perform two series of operations,one of which is a bufling operationonly, without application of polish,and the other of which is a combined bufng and polishing operation. Withthe improved mechanism, the motor is adapted to drive operatingmechanism for the brushes as well as the compressor for deliveringpolish by fiuid pressure means to the brushing zone. The rotating sidebrushes are all adapted to be constantly resiliently urged toward theopposite side portions of the shoes, and the toe brushes are adapted tobe urged toward the toes of the shoes, and these brushes are all movedover the entire surface of the shoe by the oscillatory motionhereinabove described. The various parts of the machine may be soarranged as to operate for a given period of time and with apredetermined amount of polish adapted to be automatically conducted tothe polishing zone during the full polishing operation. One of theselected series of automatic operations may obviously be initiated uponinsertion of a coin of given denomination, for example, a nickel, andthe other series of automatic operations may be initiated upon insertionof a coin of a different denomination, for example, a dime. The improvedmachine is durable in construction and all of the parts have been foundto require minimum attention, but if it is necessary to repair orreplace any parts, the parts are all conveniently accessible.

It should be understood that it is not desired to limit this inventionto the exact details of construction or precise mode of operation hereinshown and described for various modifications within the scope of theappended claims may occur to persons skilled in the art to which thisinvention pertains.
